ESPN's Buster Olney reports that the A's are on the verge of completing a one-year, $5.25 million deal with Jason Giambi.

If Olney's numbers are correct, it's a major steal for Oakland. The contract also carries an option for 2010 worth just $4 million. Giambi made $23.5 million last season and hit .247/.373/.502 with 32 dingers and 96 RBI.Source: ESPN.com Related: Athletics

Funny, I was thinking their lineup is going to be improved this year as well.Renteria is notorious for doing great in the NL and absolutely horrid in the AL.Cardinals (.300, mid teen HR) --> Red Sox (.270, below 10 HR)Braves (.300, mid teen HR) --> Tigers (.270, lower HR)

Maybe he'll do well again back in the NL, add in some young guys like Sandoval, Fred Lewis improving, the Giants offense should give some more run support to that very good starting pitching staff.
